What works better:
? Waterproof membranes
? Interior drainage
? Sump pump setups

Mistake #3: Overlooking Cracks in the Foundation
Minor cracks may seem safe, but horizontal or expanding ones aren’t. DIY kits can cover visible gaps—but not solve the cause.
Fix them by:

? Applying polyurethane-based sealants
? Adding relief systems to prevent pressure buildup
Mistake #4: Attempting Waterproofing Without Experience
Trying to waterproof yourself without knowing the risks. Many mistakes happen:
? Skipping prep
? Installing systems without inspection
? Addressing symptoms, not the cause
If unsure, schedule a consultation.
